Wang Yao had a short break at home after he came back from his grandparent's place. He went back to Nanshan hill and came across Wang Mingbao.
"Hi, what are you doing here?" asked Wang Yao.
"I need to ask you something," said Wang Mingbao.
"What?"
"My grandpa caught a cold a few days ago. He has been coughing and has a fever, and he can't sleep well at night. Could you prescribe some herbs for him? You told me you could prescribe herbs last time," said Wang Mingbao.
Wang Yao didn't hide the fact that he could prescribe herbs to his best friend.
"Has your grandpa had any medication yet?" asked Wang Yao.
"Yeah, but it didn't make much difference. His fever came back, so I'm here to see if you can help," said Wang Mingbao.
"Is it a wet cough or a dry cough?" asked Wang Yao.
"Wet cough," said Wang Mingbao.
"Okay, give me a minute. Let me see what I can do," said Wang Yao.
